To a/ZZ whom t may concern.:

Be it known that I, GEORGE S. PATRICK, a citizen ofthe United-States, residing at Waterville, in the county of Oneida and State of New York, have invented a new and useful Gate, of which the following is a specification.

The invention relates to improvements in gates.

The object of the present invention is to improve the construction of swinging gates and to provide a simple and comparatively inexpensive one adapted to be operated by the wheels of avehicle and capable of being.

opened and closed at a distance from either side of it.

A further object of the invention isto provide a gate of this character which will always open away from a vehicle, so that the operating devices may be arranged comparatively close tothe gate.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the' claims hereto appended.

In the drawings, Figure 1 is a perspective view of a gate constructed in accordance with this invention. Figs. 2 and 3 are detail views illustrating the arrangement of the oscillatory roller and the upper and lower double camplates.. Fig. 4. is a detail view of the upper and lower cam-plates and the roller, illustrating the arrangement of the parts after the lower cam-plate has been oscillated for actuating the gate. Fig. 5 is a detail view of one of the cam-plates.

Like numerals of reference designate corresponding parts in all thefigures of the drawings.

1 designates a swinging gate, which may be of any desired construction and which is hinged to a post 2 bya vertical pintle-rod 3. The pintle-rod 3, which is offset from the post, is supported by suitable brackets 4. and 5, arranged at the upper and lower portions of the post and having arms or sides secured to the posts. The brackets are also provided with projecting stems having eyes for the reception ofthe pintle-rod, and each bracket may be constructed of a single piece of metal centrally bent to form the stem and eye and l ing a loop or bight receiving thegrooved portion ofthe pulley or drum and extending from' the gate in opposite l directions to operating devices hereinafter described and adapted to be partially rotated bythe same to open and close the gate. Thelower face of the pulley or drum is provided with a metal Aplate to prevent it from being worn, and, if desired, ball-bearings or any suitable antifriction device may be employed for enabling the drum or pulley to rotate frictionflessly.

Secured to the upper face of the drum or pulley is a double cam-plate 11, having oppositely -inclined side portions extending downward and inward toward the center of the plate and adapted to receive an oscillatory roller 12, which supports a reversely-arranged upper cani-plate 13, secured to the bottom of the gate and havingyinclined side portions extending downward and outward from the center of the plate. The upper calnplate is also extended rearward from the gate and is perforated to form an eye 14. for the i` reception of the pintle-rod, and the lower cam-plate is also perforated to receive the pintle-rod. The roller, which is oval-shaped, is mounted on the outer end of an oscillatory arm 15, having an eye or sleeve 16 arranged on the pintle-rod. When the drum or pulley is partially rotated to open the gate, the lower cam-plate is carried from the position illustrated in Fig. 2, and lthe Vupper or outer edge of one inclined side portion is'carried to a point directly beneath the lower outer edge of one of the inclined side portions of the up- ICO per cam-plate, the roller being also carried outward to the outer edge of the upper plate by such movement. This operates to lift and unlatch the gate, and the two similar inclines formed by the upper and lower cam-plates cause the gate to open readily. The gate is closed by rotating the pulley or drum in the opposite direction. As the sleeve 16 is entirely independent of the upper and lower camplates, the gate is readily lifted preparatory to its swinging movement, and it is enabled to swing frictionlessly.

The pulley or drum is provided at its front with a projection 17, adapted to be engaged by the iiexible connection; but any other means may be employed for connecting the same with the pulley or drum. The gate is provided with a pivoted latch 18, adapted to engage keepers 19 and 2O of main and supplemental latch-posts 21 and 22. The pivoted latch is adapted to engage the keepers automatically, and it is disengaged from them by the vertical movement of the gate incident to the operation of the cam-plates and the oscillatory roller.

The flexible connection extends from the gate in opposite directions, and each side portion passes over suitable inner and outer guide-pulleys 23 and 24 and under guide-pulleys 25 and 26 and is secured to an arm of a rock-shaft 27. The rock-shafts forming the operating devices are provided with rectanguiar bends and are adapted to be engaged by the wheels of a vehicle in the ordinary man-l ner, and they are designed to he located a suitable distance beyond the supplemental latchpost, out for convenience of illustration are shown adjacent to the same in Fig. 1 of the drawings. Each rock-shaft is provided with a depending arm 2S, which is connected at its upper portion with the adjacent end of the flexible connection and which is provided at its lower end with a projecting portion or foot 29. The pulley 25 is located slightly beyond the depending arm of the rock-shaft when the latter is arranged in an upright position, and it is adapted to enable the arm to pull upon the flexible connection when the rock-shaft is oscillated in either direction. When the rock-shaft is moved outward away from the gate, the depending arm is carried inward, and when the rock shaft is moved in the opposite direction the depending arm is carried outward. The depending arm, owing to the foot or extension, is adapted to move the flexible connection twice as far when it is moved outward as when it is swung inward, and this will enable the gate to be operated from either side. The pulley 26 is adapted to offset the iiexible connection from the depending arm to permit the latter to swing clear of the same. The side portions of the flexible connection are maintained taut by pivoted weights 30, extending from a point in rear of the hinge-post and pivoted at their inner ends 3l to a suitable support and provided at their outer ends with arms 32, which rest upon the side portions of the flexible connections. The connections between the operating devices and the pulley or drum are designed to be mounted in a suitable trough or casing, as shown, and any other means may be employed for guiding the side portions of the flexible connection.

In a device of the class described, the combination with a swinging gate, of a pair of oppositely-disposed cam-plates arranged beneath the gate and provided with oppositely-inclined faces, one of the cam-plates being connected with the gate, means for os cillating the other cam-plate, and an oscillatory roller arranged between the plates and mounted independentlyof the same, substantially as described.

2.
